A Novel Switch-Like Function Of Delta-Catenin In Dendrite Development, Ryan Baumert
A Novel Switch-Like Function Of Delta-Catenin In Dendrite Development, Ryan Baumert
Dissertations & Theses (Open Access)
The formation of neuronal networks in the brain is tightly regulated, and dependent on the morphology of dendrites, the branch-like signal-receiving structures extending from neurons. Disruptions in dendrite development, or dendritogenesis, can lead to the atypical neuronal connectivity associated with multiple neurodevelopmental diseases. My research addresses molecular processes that underlie dendritogenesis via analysis of a pair of novel interactions involving the protein delta-catenin.
In neurons, delta-catenin localizes to dendrites and synapses, where it functions in their development and maintenance. Structurally, delta-catenin possesses a central Armadillo domain and a C-terminal PDZ-binding motif. This motif associates with PDZ domain-containing proteins, and is …
Rejuvenation Of The Epigenetic Landscape Of The Aged Brain Through Manipulation Of Circulating Factors, Edward Koellhoffer
Rejuvenation Of The Epigenetic Landscape Of The Aged Brain Through Manipulation Of Circulating Factors, Edward Koellhoffer
Dissertations & Theses (Open Access)
The aging population of the United States is expanding at an alarming rate. The Center for Disease Control and Prevention estimates that the population of those age 65 years and older will reach over 50 million by 2020 and will double to 100 million by 2060. This will not only put a massive strain on national healthcare resources, but will also increase the number of those who are not able to live and function independently. It is becoming increasingly vital to understand how the brain changes with age and mechanisms to possibly protect and rejuvenate the aged brain to a …

Development Of A High-Throughput System For Screening Of Anti-Prion Molecules, Katherine Do
Dissertations & Theses (Open Access)
The misfolded prion protein causes and transmits disease in both humans and animals. As other infectious agents, prions display strain variation, which can generate different pathological outcomes in affected individuals. Unfortunately, there are no known therapies for these diseases, which at present are invariably fatal. In this work, the Protein Misfolding Cyclic Amplification technology (PMCA, an in vitro test that replicates minimum quantities of infectious prions) has been modified to screen for small molecules inhibiting prion protein misfolding in a strain-specific manner. In order to approach a high-throughput PMCA system, technical aspects in PMCA has been optimized for application of …
Data Collection Curated With An Application Ontology Describes The Methods And Results Upon Performing An Ex-Vivo Voltage-Clamp Assay On Outer Hair Cells Of The Mammalian Cochlea, Brenda Farrell, Jason Bengtson
Data Collection Curated With An Application Ontology Describes The Methods And Results Upon Performing An Ex-Vivo Voltage-Clamp Assay On Outer Hair Cells Of The Mammalian Cochlea, Brenda Farrell, Jason Bengtson
Research Data
This data collection describes the electrical properties of outer hair cells isolated from the mammalian cochlea of the domestic guinea pig. This data was obtained by performing whole-cell patch clamp voltage clamp assay on cells and monitoring the electrical admittance during a DC voltage ramp. The membrane capacitance was then calculated at each membrane potential from this admittance, and the voltage-independent and voltage-dependent membrane capacitance was determined upon further analysis. In some case the DC conductance was also measured by interrogation of the cell with voltage-step function which was calculated from the change in the mean steady-state current with respect …
